New things are what only God can do through His unchanging nature and Almighty power.

A new thing is not an innovation from man or of man, but of God who is Sovereign, and only He can create and re-create. What is a new thing? It refers to a fresh thing and a fresh start, a brand-new thing.
Psalm 72:12-14

New things are heaven’s response to human limitations here on earth. When you feel trapped and completely overwhelmed in the old, new things are required. A detachment from the old, and separation from an unprofitable existence. It refers to the latest, having not existed before now. It is something brand new, a first time out. It is something current and refers to the most recent. It could mean a newborn, a new beginning or new birth. New things are things that God has not done before.
Isaiah 48:6-7

There must have been an old thing before the new can commence. God is declaring new things into our lives and families. We also know that His declaration cannot be hidden or covered. It is clear that what God has legislated cannot be covered nor stopped.
